HINSDALE, N.H. — A 52-year-old East Longmeadow man was involved in an ATV accident over the weekend that left a teenager from Vermont seriously injured, New Hampshire Fish and Game officials said Monday.

The accident, reported around 2:53 p.m. Saturday, happened at a trail intersection near the Hinsdale Campground at Thicket Hil. The site of the accident was on private property outside the campground, authorities said.

Conservation officer Eric S. Hannett said Michael Binney, of Waterman Avenue, East Longmeadow, was driving a trail motorcycle north when he collided with an unidentified 14-year-old girl from Bennington, Vt., who was headed east on an all-terrain vehicle. The front tire of Binney's motorcycle struck the girl, throwing her from her four-wheel vehicle, police said.

The girl, who was not publicly identified, was taken by the Hinsdale Fire Department to Brattleboro Memorial Hospital in Vermont before being airlifted to Dartmouth Hitchcock Medical Center in Lebanon, N.H. An update on her condition wasn't immediately available Monday.

Binney, who officials said declined medical attention, couldn't immediately be reached for comment. An East Longmeadow phone listing for him is no longer in service, according to an automated Verizon message.

The New Hampshire Fish and Game Department and the Hinsdale Police Department are investigating the accident.
